We use computer to perform our large amount of tasks daily. On one hand computer is making our life easier but on the other hand it is also effecting our environment. Computers produce large amount of heat and consume a lot of electricity these things effect our environment badly. Many green computing techniques have been introduced that help us to make our computers environment friendly. But there are very few techniques introduced to make our software environment friendly. Cloud computing is the process of using a network of remote servers presented on the internet to manage, store and process data rather than on a local server or personal computer. Green computing is the ecologically accountable and eco-friendly use of computers and their resources. In this research paper we will discuss those techniques and introduce a technique that will help to make our operating system environment friendly using concept of cloud computing.

Computer makes our everyday business and educational tasks very easy. Major advantage of computer is in medical field where computer is used to diagnose and treat many deadliest diseases. Modern society completely rely on computers they need computers for their safety, for their business, for their education, for entertainment, for communication.

Our research work would also be prolonged to mobile Operating systems such as Android operating systems and Apple IOS, so that charging your mobile phone becomes a weekly routine, instead of a daily business. Previously a huge amount of research has been done by Figure 2.

  • Low-Power Computing
    LOW-POWER COMPUTING Safa Alsalman a, Raihan ur Rasool b, Rizwan Mian c a King Faisal University, Alhsa, Saudi Arabia b Victoria University, Melbourne, Australia c Data++, Toronto, Canada Corresponding email: [email protected] Abstract With the abundance of mobile electronics, demand for Low-Power Computing is pressing more than ever. Achieving a reduction in power consumption requires gigantic efforts from electrical and electronic engineers, computer scientists and software developers. During the past decade, various techniques and methodologies for designing low-power solutions have been proposed. These methods are aimed at small mobile devices as well as large datacenters. There are techniques that consider design paradigms and techniques including run-time issues. This paper summarizes the main approaches adopted by the IT community to promote Low-power computing. Keywords: Computing, Energy-efficient, Low power, Power-efficiency. Introduction In the past two decades, technology has evolved rapidly affecting every aspect of our daily lives. The fact that we study, work, communicate and entertain ourselves using all different types of devices and gadgets is an evidence that technology is a revolutionary event in the human history. The technology is here to stay but with big responsibilities comes bigger challenges. As digital devices shrink in size and become more portable, power consumption and energy efficiency become a critical issue. On one end, circuits designed for portable devices must target increasing battery life. On the other end, the more complex high-end circuits available at data centers have to consider power costs, cooling requirements, and reliability issues. Low-power computing is the field dedicated to the design and manufacturing of low-power consumption circuits, programming power-aware software and applying techniques for power-efficiency [1][2].

College Woman University Sialkot Received: 06 April 2020; Accepted: 13 May 2020; Published: 08 June 2020 Abstract Cloud computing is a mechanism for allowing effective, easy and on-demand network access to a shared pool of computer resources. Instead of storing data on PCs and upgrading softwares to match your requirements, the internet services are used to save data or use its apps remotely. It perform the function of processing and storing a database to provide consumers with versatility. For specialized computational needs, the supercomputers are used in cloud computing. Because of execution of such high performances computers, a great deal of power devoured and the result is that certain dangerous gases are often emitted in a comparable amounts of energy. Green computing is the philosophy that aim to restrict this technique by introducing latest models that would work effectively while devouring less resources and having less people. The basic goal of this study is to discuss the techniques of green computing for achieving low power consumption. We analyze multiple power management techniques used in the virtual enviroment and further green computing uses are mentioned. The advantages of green computing discussed in this study have shown that it help in cutting cost of companies, save enviroment and maintain its sustainability. This work suggested that researchers are becoming ever more invloved in green computing technology.
